TCU is #6 in the BCS

[The PonyGrad]

If they only lose one they will still have a higher ranking than any MWC team. So... maybe so.

Without any inside info my guess is that they stay for now since it will cost so much in terms of exit/entrance and whatever deals they are foregoing from the CUSA.

But if MWC is hungry enough they may offer a lot. Who knows.

But if it is just an ego trip there may be no financial considerations.
